Specification forming part of Letters Patent No. 116,892, dated July l1,1871.

To all whom it may concern:

Be it known that I, NATHAN F. TURNER, of' Williamsburg', in the countyof Kings and State of New York, have invented a new and usefulImprovement in Ink Fountain for Printing- Presses; and I do herebydeclare that the following is a full, clear', J and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part of'this specification, in which- Figure l is a side view of aprinting-press to which my improved ink-fountain has been applied. Fig.2 is a top view-of the same, parts being broken away. Fig. 3 is a detailsectional view of the fountain taken through the line x x, Fig. 2. Fig.4 is a detail sectional view of' the operating parts of the fountaintaken through the line yy, Fig. 2. Fig. 5 is a detail side view of theshaft of' the fountain.

p Similar letters ofref'erence indicate corresponding parts.

My invention has for its object fo furnish an improved ink-fountain forprinting-presses, which shall be simple in construction, compact, freefrom distributing-rollers or vibrators, and effective and reliable inoperation, the ink being distributed by the form-inking rollers andink-plate or plates; and it consists in the construction of the fountainand in its combination with the various operating parts ofthe press, ashereinafter more fully described.

A is the vertical frame of the press. B is the inclined frame thatsupports the table() upon which the form is placed, and the lower partof which is pivoted to the lower part of the stationary frame A. Fromthe rear side ofthe upper part of the pivoted frame B project arms D, tothe rear ends of which are attached the ends of the cross-bar E, uponthe center of which is formed, or to itis attached, the pivot or spindleF, upon which the inking-plate or plates G revolve. The plate or platesGr are revolved by the pawl H and bent lever I, which operate upon theratchet-wheel J formed upon the under side of' the said plate or platesG, and are operated by their own weight and the movements of' thepivoted frames l5, D, and K.. The frame K is pivoted to the arms D of'the pivoted frame B, and in slots in the forward ends of its side barswork the journals of the hiking-rollers L. M

are connecting-bars, the forward ends of which are pivoted to the upperparts of' the stationary frame A, and the rear ends of which are pivotedto the side bars ofthe frame K, or to short arms or lugs formed upon orattached to the frame K a little above and in front of the points atwhich the said frame is pivoted to the arms D of the frame B. N areconnecting-bars, the rear ends of' which are pivoted to thepivots thatpivot the frame K to the arms D of the pivoted frame B. The forward endsof' the bars N are pivoted to the crank-pins attached to the wheels Uattached to the ends of' the shaft I), which works in bearings in theupper part of' the frame A. By this construction, as the shaft P isrevolved the frames B, D, and K, are drawn forward. But, the forwardmovement of the upper or forward part ofthe frame K beingI prevented bythe connecting-bars M, the said bars M cause the said parts ofthe saidframe Kto move upward, causing the form-inking` rollers L to roll upalong the front of' the frame and the surface of the inkdistributingplate or plates G. Q is the ink-box, trough, or receiver of thefountain, and is attached to the upper end of' the arm R, the other orlower end of which is bolted to the ends of the cross-bar E and arm D bythe same bolt that secures said parts E D to each other. S is a shortshaft working in bearings in the-forward end of the box Q, and uponwhich, in the open forward end of the said box Q, is placed a smallroller, T, by which the ink is transferred to the inking-rollers L. Theroller T is connected with the shaft VS by a short pin, S', attached tothe said shaft S, and which enters a groove in the inner surface of thesaid roller T, as shown in Fig. 3. U is a slotted arm, which rides uponthe end of the shaft S, and the lower end of' which is connected withthe frame K and bar M at or near the point at which said parts arepivoted to each otheyy a cord, V, so that the said arm U may be peratedby the movements of the said parts K M. Upon the shaft S, and within theslot ofthe arm U, is placed a ratchetwheel, W, which is operated upon torevolve the shaft S and roller T by a pawl, X, pivoted in the upper partof the slot of the arm U, and held down upon the teeth of the saidratchet-wheel W by its own weight. The ratchet-wheel W s connected withthe shaft S, so as to carry the said shaft with it in its revolution, bya short pin, s2, attached to the said shaft., and entering a groove inthe inner surface of the said wheel, as shown in Fig. 4. The bearingsfor the shaft S in the box Q and arm U are notched or grooved for thepassage of the two short pins attached to the said shaft S, so that theshaft S may be conveniently removed when required for cleaning theroller T, or for any other desired purpose. The shaft S is secured inplace, and, at the same time, allowed to revolve freely7 bythehook-catch Y pivoted to the side of the boX Q, and hooking into a grooveformed upon the projecting forward end of the shaft S.

By this construction, every time the form-inking rollers L pass up, theend of the forward roller, outside of the line of contact with the form,comes iu contact with the roller T and receives a supply of ink, whichit transfers to and distributes upon the plate G near its edge. As

the plate or plates G are carried around the ink 1s still furtherdistributed before it is brought in contact with the part of the saidrollers that transfers it to the form. The amount of ink taken up by theink-roller T and transferred to the forin-inking rollers L is regulatedby the knife A placed in the bottom of the boX Q and adjusted by asingle set-screw, B', as shown in Figs. l and 3.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In an inking apparatus, consisting of inkingrollers LL and distributing-disk G operated as described, the short ink-fountainQ A T located at one side thereof, substantially as and Vfor the purposeset forth.

The above specification of my invention signed by ine this 23d day ofSeptember, 1870.
